Many of our products are designed to be controlled with a PLC; including the EMP series controllers. Please see the following wiring diagram for the CN1 connector on the EMP controller (scroll down to view entire diagram; inputs on top/outputs at bottom):

Your PLC would be the "host controller etc." on the left. There's only one way to wire the EMP controller, so just follow the wiring diagram.

The EMP outputs are open-collector types so you'll actually have to supply 5 to 24VDC to our outputs from your PLC's input. All our output circuit does is open and close the transistor to GND. If no voltage is supplied from the PLC side, then no voltage will be output when the output turns on/closes. You'll need PNP output transistors on your PLC's input side since we're sinking on our side.

You will also see from the wiring diagram above that you can only use NPN transistors with our CN1 inputs.

Our newest controller, SCX11, offers both sink/source as well as 5v/24v I/O capabilities and a GUI software. It may work for you, but it's only designed to control one motor/driver at a time. The EMP402 model is a dual-axis controller. For more information on any of our product models, please do a part number search on our main website.

The READY output will only turn on when a program is not already executing or being modified. Do you have a program named "99" or "CONFIG"? Type "EDIT" and then ENTER to get into your program directory to see if that program exists. Program "99" automatically executes upon power-up or RESET command. Either delete that program or change the name to something else. You can also tell if a program is already running by simply trying to run another program. If a program is already running, it cannot execute another program. It will give you an error message. Press the ESCAPE key to immediately exit the program.

If the READY output bit never changes to "1" or on in the R status report, then we may have a damaged output circuit. The ALM and READY outputs wire to the EMP in exactly the same way.

Do you have any alarms? What type? Do you have the E-STOP input wired to -COM?
